Sounds like you could make an excellent bait by mixing the molasses & tallow with the corn (used as a binding agent). I've used molasses & suet blocks (rendered beef tallow & seeds formed into blocks for bird feeders) with great success in the past. Mix the ingredients into a paste-like consistency and apply to stumps, logs, tree trunks, inside of bait barrels, etc. at your bait site. This way the bear can't carry away the bait & eat it out of sight, forcing him to remain at the bait site, thus giving you more shooting opportunities.
Cheap bait is good...free bait is BETTER!
